全玻璃幕牆——辦公大樓

35 Lower Long是一座86米高的優雅玻璃幕牆辦公大樓，最近落成，將為開普敦新興的金融和酒店區注入活力。

該建築由Abland地產開發商開發，dhk建築事務所設計，其特點是透過動態的玻璃平面，無縫地延伸到辦公室和停車層，形成獨特的雕塑體量。

建築物的兩個主要角落向屋頂線倒角，並向上聳立，形成引人注目的翼狀效果——為開普敦的天際線增添了一個獨特的、非正交的元素。

35 Lower Long， an elegant 86-metre glass-clad office tower， has recently been completed which will invigorate Cape Town’s emerging financial and hospitality district。 The building， developed by Abland Property Developers and designed by dhk Architects， is characterized by a singular sculpted massing which is transformed via dynamic glazed planes that extend seamlessly over the office and parking levels。 The two main corners of the building are chamfered towards the roofline and soar upwards， forming a striking wing-like effect – resulting in a distinctive， non-orthogonal addition to Cape Town’s skyline。

由於核心設計不切實際，增加樓層的侷限性，需要更換過時的外牆，以及長期可行性的挑戰，最初的改造和擴建現有的20世紀80年代建築的方案被放棄。

由共同業主Ellerine Bros和Abland修改後的方案是提供一個更積極的中長期可行性，以及透過一個更高的、鼓舞人心的塔式建築來提升開普敦的天際線。

然而，面臨的挑戰是如何在相對較小的樓板內，最大限度地提供優質的多租戶商業空間，同時容納電梯和樓梯等核心部件，以及一個地下停車場。

The initial brief to remodel and extend the existing 1980s building were discarded due to impractical core design， the limitations of adding floors， the need to replace an outdated façade and challenges with long-term viability。 The revised brief， by the co-owners Ellerine Bros and Abland， was to offer a more positive medium- to long-term viability， as well as to enhance Cape Town’s skyline with a decidedly taller， inspirational tower building。 However， the challenge was to maximize the quality multi-tenant commercial space while accommodating core components such as lifts and stairs along with structured basement parking - all within a relatively small floor plate。

為了最大限度地利用樓板，香港建築大學建議在東南角和西南角的銜接處採用簡單的單體正交體量。

雖然從根本上講，這是一個堅實的建築體量，但透過錐形或曲柄形的立面，創造了一個動態的、非正交的雕塑體量，並無縫地延伸到辦公室和停車場層。

這是透過在正交停車基座的頂部對建築的東南角和西南角進行倒角，並將其向屋頂拓寬來實現的。這種技術使建築的立面銜接起來，並在翼形立面和延伸到頂層辦公樓層時，使建築四角的實體性減弱。

透過將翼形立面屏風延伸到屋頂水平以外的護欄斜面，創造了高聳的碎片的外觀，而不是產生突兀的終止感。

To maximize the floor plates， dhk proposed a simple singular orthogonal massing bar the articulation of the southeastern and southwestern corners。 While fundamentally a solid building mass， the appearance of a dynamic， non-orthogonal sculpted mass was created via tapering or cranked façade planes which extend seamlessly over the office and parking levels。 This was achieved by chamfering both the southeast and southwest corners of the building at the top of the orthogonal parking base and widening them towards the roof。 The technique articulates the façade and defragments the solidity of the corners of the building as the wings shape the elevations and extend past the top office floor。 By extending the wing-shaped façade screens beyond the roof level with parapet sloping， the appearance of soaring shards is created opposed to an abrupt utilitarian termination。

在材料方面，選擇玻璃幕牆是因為它的平齊和雕刻的反射形式能夠掩蓋停車層和固體的懸垂。

玻璃不僅促進了令人激動的光的發揮，而且允許在屏風和鯊魚鰭般的元素中表達建築體量。

在停車場層、天花板空隙、結構和內部辦公桌高度的立柱上引入畫素化，使建築既隱藏了停車場層，又避免了高聳的水平帶帶來的單調感。

In terms of materiality， a glazed façade was selected due to its flush and sculpted reflective form which is able to conceal both the parking levels and solid spandrels。 Not only does glass facilitate an exciting play of light but it allows for an expressive articulation of the building mass in the screen and shard-like elements。 The introduction of pixilation on the portions fronting the parking levels， ceiling voids， structure and internal desk height upstands allows the building to conceal both the parking levels and avoid overbearing horizontal bands。
